12 Claims.

This invention relates to a mechanical operator and particularly to ajalousie operator.

A main object of the present invention is to provide a mechanicaloperator which can be used to adjust a wide range of devices such asvalves, dampers, pushing devices for turn tables or platforms, etc., andin fact any device where load reactions on the controlled device mightdisturb the adjustment and wherever the use of a single force to bothunlock and actuate the operator would be necessary or convenient.Although the invention will be described in connection with a jalousieoperator, the invention is not intended to be limited by thisdescription unless specifically set out in the claims.

A principal object of the present invention is to provide an improvedjalousie operator, and particularly to provide a self-locking jalousieoperator, operable to automatically unlock to perrnit operation thereofand therefore adjustment of the slats of a jalousie, and toautomatically resume a locking condition after adjustment of the slatsto thereby retain the slats in adjusted position.

Another object of the present invention is to provide a self-lockingjalousie operator as above described which is simple and inexpensive inconstruction, reliable in operation, compact, and readily applied to'awindow frame.

Various other objects of the present invention will be apparent from thefollowing description taken in connection with the accompanying drawingsin which:

Fig. 1 is a fragmentary cross-sectional view in side elevation through awindow of the jalousie type having ajalousie operator of the presentinvention incorporated therein.

Fig. 2 is a fragmentary cross-sectional view in side elevation takenthrough the jalousie operator disclosed in Fig. 1 and showing the partsof the jalousie operator in the positions they occupy when the operatoris locked and when the slats are in closed position.

Fig. 3 is a horizontal cross-sectional view taken along line 33 of Fig.2 in the direction of the arrows.

Fig. 4 is a vertical cross section taken along line 44 of Fig. 2 in thedirection of the arrows.

Figs. 5 and 6 show diagrammatically the positions occupied by certain ofthe parts in the jalousie operator when the operator is being operatedfor movement in opposite directions.

Referring to the accompanying drawings, wherein similar referencecharacters designate similar parts throughout, Fig. 1 shows a jalousieoperator generally indicated as 9 being mounted on a jamb ll) of awindow frame generally entitled l l and connected by a link it to atravel bar i5. Travel bar is is connected by levers I? to a plurality ofslats is which are adapted to be adjusted in various angular positionsthrough operation of the jalousie operator 9. Slats 19 are pivotallyconnected at 2! to the jambs of window frame i l, the generalconstruction of such a jalousie window not being a particular part ofthe present invention and therefore only described generally.

Jalousie operator 9 includes a case 22 containing a part of theoperating mechanism of the jalousie operator. Case 22 assumes the formof an open box casting recessed in jamb l0 and held in place by amounting plate 23, secured to the case by screws 23a and to the jamb byscrews 23b. There is an escutche'on plate 24 secured to the righthandwallof case 22 by screws 24a and to the jamb ill by screws 24b. Theoperating mechanism 01- the jalousie operator 9 includes a first classcomposite lever 25 which is pivotal about a pivot pin 21, and at itsinner or lefthand end, as the parts are depicted in Fig. 2, isoperatively connected to a lever-actuated vertically movable travelingyoke 29 by a pivot pin 3! and a roller 32 carried thereon and disposedwithin the groove of a horizontally grooved guide block 33 which issecured to travelingyoke 29 by rivets 3 Guide block 33 permits lateralmovement of the arcuately movable pivot pin 3! and roller 32 relative tothe linearly movable traveling yoke 29' upon operation of lever 25.Traveling yoke 29 is connected by a pivot pin 35 to previously mentionedlink l3 whereby slats l9 can be opened, closed or adjusted to anyintermediate position by operation of lever 2 5.

Mounting plate 23 has an oblong slot 35 therein through which pivot pin35 extends and within which pivot pin 35 travels. Jamb it is suitablyrecessed to accommodate the movement of yoke 29. Escutcheon plate 24 andthe wall of case 22 to which it is attached have registered oblongopenings formed therein to accommodate the movement of lever '2 5.

To hold slats l9 in any desired position of adjustment, a releasablelocking mechanism is provided. This locking mechanism includes a lookingrod 31 secured at its ends by screws 38 to end flanges 38a on yoke 29and slidably receivable through the upper and lower walls of a case 22and through a pair of latching plates 40. Latching plates 40 arepivotally mounted at their lefthand ends, as the parts are depicted inFig, 2, in

U notches 40a formed on case 22, and urged apart by a compression spring4| secured to the plates by rivets 4 a.

Latching plates 40 have the apertures thereof, receiving locking rod 31,of a size to loosely receive the locking rod so that the latchingplates, under the influence of compression spring 4|, assume positionsangularly transecting the locking rod. Since such latching plates are,per se,

old in the art apart from the present combination, it is apparent tothose skilled in the art that the upper latching plate will preventupward movement of locking rod 31 and the lower latching plate willprevent downward movement of locking rod 31.

For automatically effecting a release of latching plates 45, a releasemember 43 is provided and pivotally mounted at its lefthand end to case22 by a pivot pin 47 and operatively connected by the previouslymentioned pivot pin 21 to composite lever 25. It is apparent that pivotpin 3| will be held stationary and therefore lever will be heldrelatively stationary, by the engagement of latching plates with lookingrod 37 until a release of the appropriate plate is effected, and,therefore, during the first increment of movement of lever 25 in eitherof its directions of movement, lever 25 functions as a second classlever, pivoting about pivot pin 3| and swinging release member 43through the medium of pivot pin 21 in the same direction of movement asthe handle end of lever 25.

However, only limited movement of release member 43 is permitted, saidrelease member at its righthand end engaging a stop 49 when lever 25 ispivoted clockwise, and engaging a stop 56 when lever 25 is pivotedcounterclockwise, said stops being formed on case 22 (see Figs. 5 and6). After engagement with either stop 49 or 50, release member isstationarily held and lever 25 thereafter operates as a first classlever to urge traveling yoke 29 in the opposite direction from whichforce is applied to the handle end of the lever. In order to release theyoke for movement, release member 43 has a pair of latch-engaging screws5| threadedly received by offset ears 52 formed on release member 43.One of the screws 5| is adapted, when the release member is moved in onedirection, to engage the adjacent latching plate, and the other of whichis adapted to engage the other latching plate when the release member ismoved in the opposite direction. (Compare Figs. 5 and 6). Suchengagement moves the latching plates, individually and separately, fromtheir normal latching positions to positions where their bores are morenearly aligned with looking rod 31, and holds the latching plates,individually and separately, against pivotal movement in the directionurged by locking rod 31, thereby permitting the locking rod to slidethrough the latching plates and therefore permitting adjustment of slatsl9 by operation of lever 25. Release member 43 is moved to anon-releasing position, after lever 25 is released, by a leaf springsecured at one end to case 22 and at its opposite end to release member43. Release member 43, during such movement, carries lever 25 therewith,the operative connection of pivot pin 3| and roller 32 in guide block 33permitting such movement of lever 25.

Screws 5|, by virtue of their threaded engagement with cars 52, areadjustable toward and away from their respective latching plates, andadjusted so that when release member 43 is in 2 its non-releasingposition, the inner opposed ends of the screws are disposed closelyadjacent to but spaced from their respective latching plates. Screws 5|are held in their adjusted positions by compression springs 51. Screws5| have hex heads to facilitate easy adjustment of the screws.

Composite lever 25 includes a tapered socket portion SI and a removablytapered handle portion 63 fitting in the socket portion. The handleportion is preferably removed after adjustment to avoid possible injuryto a person passing the window.

Although the operator is shown as being directly manually operated, itis apparent that the device could be remotely controlled such as byrope, chain or push rod arrangement.

By the present invention, a jalousie operator has been provided which isself-locking so that while it may be readily operated to adjust theslats of a jalousie window construction to any desired position, thejalousie operator is operable to prevent movement of the slats initiatedby a force imposed directly on the slats or in any other manner exceptby a force imposed on the lever.

While I have shown the preferred form of my invention, it is to beunderstood that various changes may be made in its construction by thoseskilled in the art without departing from the spirit of the invention asdefined in the appended claims.
